[SOLVED] class set var=false

[jonniejoejonson]

I have the following:

 

class testClass{

var $testVar=false;}

 

$testObj = new testClass;

 

if(isset($testObj->testVar)){

print 'testVar is present';}

 

the result is that it prints - 'testVar is present' ...

yet i have it set to false...

where am i going wtrong.. kind regards J.

you have SET it!

 

isset will check to see if the given argument is set.

 

if ((bool)$testObj->testVar === false) is more like what you are after.

That will be the answer... thanks...

Can i ask one more question... what is the difference between

===

and

==

thanks J

[Zane]

=== means that they are equal AND they are the same type... like...for instance..a string or integer

 

for example:

$thevar = "42";

$thevar2 = 42;

 

$thevar === $thevar2 would be false...because the first one is a string, while this next one is true

$thevar == $thevar2 /// TRUE

Thanks zanus, that makes sense... regards J
